Homework Help: Reaction Prediction - Is there a reaction?

  1. Feb 26, 2012 #1
    1. The problem statement, all variables and given/known data
    sodium oxide plus water --> ?
    Is there a reaction?

    2. Relevant equations
    sodium oxide plus water yield sodium hydroxide

    3. The attempt at a solution
    Na2O + H2O --> 2NaOH

    I don't understand whether or not there is a reaction. The problem does not give any states of matter, so how can I determine whether or not there is in fact a reaction?

    I was hoping for something a little more general, Bipolarity.
    As in, how can one tell whether or not there is a reaction, without googling to find out.

    Metal oxides are basic, particularly those of the Group I and Group II metals. This means they produce hydroxides when dissolved in water.

    So you have,
    Metal oxide + Water --> Metal hydroxide
